TrueNAS SCALE 23.10 has the Fastest Growth Ever


December 20, 2023

TrueNAS SCALE 23.10 “Cobia” was released in October and already has over 30,000 deployments, setting a new record for TrueNAS adoption rate. The third major release of TrueNAS SCALE has delivered improvements in quality, functionality, security, and performance. Along the way, TrueNAS SCALE has reached the multiple exabyte milestone, with over 100,000 systems and 2,000 petabytes of storage managed. Today, we are releasing the first major update to Cobia, TrueNAS SCALE 23.10.1.

TrueNAS SCALE 23.10.1 includes almost 200 bug fixes and improvements, including a fix for the 15-year-old ZFS bug that was recently discovered. There are several improvements to GPU isolation handling, and the ‘statistics export’ API to Graphite has been reactivated. SCALE users can now make use of Apps such as Grafana and Prometheus for additional real-time monitoring and reporting of their TrueNAS statistics.

Please read the release notes before updating. This update is recommended for early adopters until there has been more testing and feedback from the Community. Visit the TrueNAS Software Status Page for our most up-to-date recommendations.

TrueNAS Enterprise appliances with 23.10.1 begin shipping in early 2024. These include the following TrueNAS appliances:

  • F-Series: New high-performance, all-NVMe HA systems
  • M-Series: Scalable systems with HA supporting up to 25PB
  • X-Series: 2U energy-efficient HA systems
  • R-Series: Single controller systems with the lowest price per TB

TrueNAS 13.1 Will Inherit Some Cobia Improvements

Nightly versions are available for testers and those who wish to help contribute to TrueNAS development. The link to the nightly versions can be found on the TrueNAS Software Status Page.

TrueNAS SCALE 23.10 is now the Default for SCALE

TrueNAS SCALE inherited storage functionality and automated testing from CORE. Based on Linux, KVM, and Kubernetes, SCALE offers a more robust environment for apps. To join the >100,000 users already using TrueNAS SCALE, download the installer here or use the System Update feature from within your existing TrueNAS install.

Work has already begun on the next TrueNAS SCALE release, codenamed “Dragonfish”. There will be updates on this plan in February 2024.

TrueNAS provides these choices and the ability to automatically migrate storage services and VMs from CORE to SCALE. Plugins and jails in CORE can be manually replaced with Apps in SCALE. We encourage anyone looking for further advice or answers to questions to visit our Community Forums or Discord Channel.
